And this sigma is not only example. Two Tokina SD 400/5.6 went for over 600 USD and sigma non-apo AF 400/5.6 was sold for over 450 USD. What is going on?

I'd buy a new Samyang 14/2.8 for less than half that price.

Pentax second-hand market is crap, most of the old lenses are overpriced. It can be due to low numbers on market, to higher number of "collectors" than other brand, whatever. People seem to love to spend lots of cash on old manual lenses, designed for film.

I think all we are seeing is that as there are more and more Pentax bodies out there, the price will go up, we are seeing the impact of success.

A few years ago, before sigma released the APO 70-200 F2.8 EX DG Macro, you could not get a 70-200 in k mount. The older versions were selling used after 4-5 years for more than they sold new in 2003-4, I am glad I didn't sell because the macro version is softer wide open especially at 200mm

there are people buying lens for its performance/price ratio, and there are also people buying lens for collection

When I started buying used Pentax gear in the early 2000's I kept a Lens Lust List made up of the lenses I dreamt about but would never have a chance to own. At one time all it had on it was:
  • FA*28~70/2.8
  • FA*80~200/2.8
  • FA*250~600/5.6
  • The three FA Limiteds
Even today that kit of six lenses would satisfy every need I could ever have, and I could never utilize their protential.

I'm, kinda confused though. What would be the difference with the 15mm A vs the 15mm LTD? Both 15mm, shouldn't they give the same image size?

Yep, makes it hard for non collectors to afford them. But it is not crap for the collectors, just crap for the non collectors. The collectors investment seems to only go up.

Hi to all,
I have the same concern. The same seller sold Sigma 100-300/4 in K mount for 1470 USD. Yes, it is amazing and very rare lens. But 1470USD!!!! It is really strange. Why K mount lenses are more expensive than the same lenses for other systems? Is it because of there rarity?
Best regards,
Yuriy

Just a great lens and hard to come by. Lots of $$ out there as well. If a Wall Street buyer had a hard on for it they could have spent $5,000 and not blinked.

The 15ltd is a digital lens, no aperture ring - the 15mm A is has a well dampened MF ring. As noted earlier in this thread, these older SMC 15's are being bought up for video use with maybe the exception of one here and there for other purposes.

The DA Ltd only covers APS-C, just over 15mm radius image circle.
The A covers FF, well over 20mm radius.

How could thaty be if both are 15?

Is the digital 15 really not a 15 and just called a 15 so the film shooters can relate to it's image size?

They both have a focal length of 15mm, but while the image circle of the A series covers the full frame, the one of the DA series (with exceptions) only covers the APS-C sensor size without vignetting.

Both have 15mm focal length.

Take your camera with the 15mm A. Expand the viewfinder a bit over 25% in every direction. That's the 15mm A on a full frame camera.

With the 15mm limited, those 25% of the viewfinder would be darkened/black.
